He was a member of the Neo-Concrete Movement. In 1963 together with Willys De Castro, Lothar Charoux, Waldemar Cordeiro, Lygia Clark, Luiz Sacilotto among others, Barsotti became one of the founders of the São Paulo based art gallery Associação de Artes Visuais Novas Tendências which operated until 1965. Associação de Artes Visuais Novas Tendências was founded and managed by artists working within the Concrete and Neo-Concrete movements but did not solely feature Concrete and Neo-Concrete art. The galleries goal was to provide a space and platform for contemporary art to be presented outside the confines of any particular artistic movement.
